摘要： Compositions comprising at least one C4-C30 olefin or oxidation product thereof and kerosene or an aromatic solvent are particularly effective for use in removing asphaltene and asphaltene-containing organic deposits and in preventing or reducing the precipitation and deposition of asphaltenes from hydrocarbon fluids. When added to heavy oils comprising asphaltenes, alone or in combination with dispersants and further inhibitors, the invented compositions lower viscosity and pour point, and aid in preventing asphaltene precipitation during transport and in combustion.
摘要翻译： 包含至少一种C 4 -C 30烯烃或其氧化产物和煤油或芳族溶剂的组合物特别有效地用于除去含沥青质和含沥青烯的有机沉积物，以及防止或减少烃流体中沥青质的沉淀和沉积。 当添加到单独或与分散剂和进一步的抑制剂组合的沥青质的重油中时，本发明的组合物具有较低的粘度和倾点，并有助于防止在运输和燃烧期间的沥青质沉淀。
